SIDI CROSSAIR HD BILLY BOLT 2025 - PINK WHITE

A boot that sets the bar higher. Developed and used by professional hard enduro rider Billy Bolt. 

The Crossair HD isn’t just a boot, it’s a game-changer. Developed and ridden by professional hard-enduro ace Billy Bolt, it’s the world’s first boot built specifically for hard and super enduro. Combining the durability and quality of a premium Sidi with a feather-light weight of just 1700 grams (size 43), it’s far lighter than anything else out there.

Inside, a fiberglass-reinforced exoskeleton delivers full support and protection without weighing you down. The specially designed rubber sole, stitched directly to the upper, draws from trial-boot technology to give unmatched grip on the pegs and across any terrain you tackle. Every detail of the Crossair HD comes from Billy’s exacting standards, blending his signature style with Sidi’s engineering expertise to create a boot that’s protective, precise, and ready to push limits.
